Recent reports coming out of the Park have been all about good surface activity on dry flies as the days wear on into the post-noontime hours. This is a common story for this time of year as the fish turn on a bit more with warmer temps during the 12-5 PM or so time of day. Recent trips have seen success on dry dropper rigs with Green Drake patterns and #16-18 Parachute Adams in the lead dropping to small midges such as a Zebra in sz 20-22. Don't forget about small terrestrials (beetles and ants) for the first couple of weeks in October, too. 6x tippet is mandatory at this time of the year, and a longer leader can help your case in some situations. A good rig for the warmer, sunnier days in late Sept./early Oct. is a small #18 Elk Hair Caddis in the lead dropping to an unweighted emerger or soft hackle-type bug (Pheasant Tails and RS2s are favorites) in #18-20. Fish in the park often like small, unweighted nymphs in the fall, especially in the shallower pockets and pools where bumping the bottom with a tungsten beadhead starts to feel like overkill. High lakes in the park will be slowing down, but should still fish for at least the next week or so, depending on the elevation. Think leeches and midge patterns at the lakes, and tie on with 6x fluorocarbon for your best chance at hookups in the clear, still water.

The Ultimate Fly Fishing Report
Casting a fly in a tranquil mountain stream, feeling the tug on the line, and holding a beautiful rainbow trout makes us feel alive and intensely connected with nature. Fly fishing is our way of life and we are blessed with hundreds of nearby rivers and streams just a short distance away from Boulder. From the swift spring waters of the Clear Creek to the meandering bends of the South Platte, it's critical to consider fishing conditions in advance and prepare accordingly. We rely on our experienced guides who venture into the wild to let us know which rivers favor fly fishing, where fish are biting, and which fly patterns are most effective. Planning a successful fishing trip also requires knowledge of stream flows at various river points and an accurate weather forecast for a given destination. At Rocky Mountain Anglers, we are dedicated to providing all avid anglers with detailed and timely information about hatches, water, and weather conditions. So before you head out the door on your next fishing adventure, visit our web site to find valuable information that will prepare you for a successful trip. Have fun chasing after your next trophy trout and enjoy nature's beauty!The Rocky Mountain Anglers Crew
